Did you feel today's earthquake? I didn't. According to the USGS the earthquake happened at 1:37pm CT and was centered around East Prairie, Missouri.
Here is the shake map from the USGS where they compile "I felt it" reports submitted through the internet.
Earthquakes around here aren't too uncommon but when you combine today's earthquake with the Chile and Haiti quakes people start talking.
I wanted to find out how common or uncommon a 3.7 magnitude earthquake is in the KFVS viewing area (southeast Missouri, southern Illinois, western Kentucky, and northwest Tennessee). It turns out that since 1974 we have had 12 earthquakes of a 3.7 or greater magnitude.
Below is the map with the location/intensity of the quakes in the area since 1974.
